Hi Guys,

We use the 2.7 version of the YUIUploader (and the swfuploader version needed to work w/ 2.7).

In the development box, no problem. Upload works.

However, when the application was deployed in a server set-up, "Error 2038" gets triggered by the onUploadError event. It never recovers from there - uploading stalls for the rest of files.

Any ideas what could be causing this?

Thanks!

Error 2038 is a general I/O error thrown by Flash, and could be caused by many possible reasons. Look at the transaction through Wireshark. What are the request-response heuristics? What is the delta between a successful and an unsuccessful upload?

- Is there a proxy between the client and the production server? (You should be able to confirm this with Wireshark if an error occurs here.)
- Aggressive AV may also trigger this error.
- Are the security rules different on the development box versus the production box?
- Invalid URI? (This may be reported as 2038, as well.)

Regards,
Thomas

Is there a pattern to the success or failure of a transaction, based on the size of the file? Do you notice this happening consistently with small files or large files?

In looking at the exception, I am guessing there is something in the multi-part message that may be malformed, causing the stream to terminate. Also, the file's content-type will be reported as "application/octet-stream," if that makes a difference; content-disposition will be as expected, without modification.

I cannot say if this is a packet issue, though, without comparing the packet activity between a success case and a failure case.

I have the same problem. The same media gets uploaded fine some times and fails sometimes. I took the tcp captures. Wire shark says [TCP previous segment lost] A segment before this frame was lost.
any idea what could be causing this error.

What can you tell me about the development environment versus the production environment? The difference in behaviour between the two may suggest something different in each Web server's configuration; and, may help debug the situation further.
